MOSES CRAWFORD, OF INDIANAPOLIS, INDIANA.

SPECIFICATION forming part of Letters Patent No. 248,087, 'dated october11, 1881.

To all 'whom it may concern Be it known that l, MosEsGRAwFoRD,-of thecity of Indianapolis, county of Marion, and State of Indiana, haveinvented certain new and useful Improvements in Hog- Scrapin g Machines,of which the following is a specilication.

The object of my said invention is to so arrange thecarrier-chain andcatch-pan of a hogscraping machine as to permit the more convenientattachment of the hogs carcass to the former and the more convenientremoval of the hair from the latter, as will hereinafter be morespecically explained.

Referringto the accompanying drawings, which are made a part hereof, andon which similar letters of reference indicate similar parts, Figure 1is a vertical section of so much of a hog-scraping machine to which myimprovements are applied as is necessary to exhibit said improvements.Fig. 2 is a plan of said improvements looking downwardly from the dottedline a: in Fig. 1.

In said drawings, the portions marked A represent the scraping-cylinderof the machine; B, the carrier-chain; C, D, E, and F, pulleys orsheaves,over which said chain runs; G, the scalding-tub; H, Va platformat the end of said tub I, a second platform, preferably formed of slats,and running from near the platform E to underneath the cylinderA; J,cross-bars which support the slats I; K, a pan underneath the platform Iand the cylinder; L, a perforated top covering said pan; M, a pipeconnecting said pan and the scalding-tub, and N, an open space betweenthe scal'ding-tub and the pan.

The cylinder A contains the scra ping-knives of the machine. (Notshown.) It may be'of any construction desired, but is shown as a plaincylinder.

The carrier-chain B is used to draw the carcass from the scalding-tub(starting from the wheel D) up through the scraping-cylinder orScrapers. Returning, it passes over the perforated pan-top L, and rakesthe hair therefrom in its passage into the space N. It maybe either inthe form ofa single chain or ofa chainladder, according to therequirements of the machine.

The pulleys C, D, and F are common pulleys Application filed August E,1881. (No model.)

or sheaves, mounted in fixed or stationary bearings, over which thechain B runs. The pulley E is a tightener, and is operated in a movablebearing by a screw, E', as shown.

The scalding-tub G is of the common construction. Itis located farenough from the scraping portion to leave room for the operatives towork to advantage.

The platform H is located at the end of the tub nearest to the machine.`It is preferably somewhat inclined toward the point where the carcass ishooked onto the carrier-chain, so as to facilitate moving said carcassin that direction. The carcass is thrown out of the tub onto thisplatform by the usual levers employed for the purpose. (Not shown.)

The slatted or open work platform I permits all the water which drainsfrom the carcass during its passage toward and through the machine, asalso the water and hair which fall thereon from the machine itself, topass freely through onto the top of the pan below.

The pan K receives the water which comes from above, which is conveyedthereform into the scalding-tub G through the pipe WI.

The perforated top L, while it permits thc free passage of the waterinto the pan, prevents alike passage of the hair, which is retained ontop until conveyed away by the returning portion of the chain.

The carcasses can be handled much easier when the platforms HandIaroused than when it is attempted to attach them Ito the carrierchainwhile in the water. J

The water which comes from the machine is by the means describedconveyed into the scaldiug-tub with little orno Wastage, While the hairis effectually prevented from getting therein, but is discharged fromthe machine outside, whence it can be conveyed away at pleasure.

' The operatives are all given sufcient space in which to advantageouslydo their work by this arrangement, which is perhaps as importantas anyofthe advantages which resulttherefrom.

Having thus fully described my said invention, what I claim as new, anddesire to secure by Letters Patent, is

1. The combination ofthe scraping portion or cylinder of a hog-scrapingmachine, the scalding-tub, an intermediate platform, and a IOOcarrier-chain, which passes over said platform on its way to saidscrapingportion or cylinder, substantially as and for the purposes setforth.

2. The combination of the cylinder A, the chain B, the pulleys C, D, E,and F, the scalding-tub G, the platforms H and I, the pan K havingperforated top L, and the pipe M, all arranged and operatingsubstantially as shown and specified.

3. The combination of the scraping portion or cylinder of a hog-scrapingmachine, a platform leading thereto, and a pan beneath said platform andsaid cylinder to catch the water and convey it to the scalding-tub, whenarranged and operating substantially as set forth.

4. The combination of the scraping cylinder or portion of a hog-scrapingmachine, a pan arranged beneath said cylinder or portion having aperforated top, as specified, to catch the hair as it falls from themachine and prevent it from going with the Water into the pan, and thecarrier-chain, which passes over and near to said perforated top on itsreturn from the scraping portion toward the scalding-tub and draws theaccumulated hair from on said perforated top to a place of depositbetween the pan and the tub, all substantially as set forth. .In witnesswhereof I have hereunto set my hand and seal, at Indianapolis, Indiana,this 2d day of August, A. D. 1881.

MOSES CRAWFORD. In presence of- C. BRADFORD, GEO. A. LoWRY.
